Particle pollution (also known as "particulate matter")

  • in the air includes a mixture of solids and liquid droplets. Some particles are emitted directly; others are formed in the atmosphere when other pollutants react. Particles come in a wide range of sizes. Those less than 10 micrometers in diameter (PM10) are so small that they can get into the lungs, potentially causing serious health problems. Ten micrometers is smaller than the width of a single human hair.
    • Fine particles (PM2.5). Particles less than 2.5 micrometers in diameter are called "fine" particles. These particles are so small they can be detected only with an electron microscope. Sources of fine particles include all types of combustion, including motor vehicles, power plants, residential wood burning, forest fires, agricultural burning, and some industrial processes.
    • Coarse dust particles. Particles between 2.5 and 10 micrometers in diameter are referred to as "coarse." Sources of coarse particles include crushing or grinding operations, and dust stirred up by vehicles traveling on roads.
Sources of Particulate Matter
--> What are the sources of Particulate Matter (Particle Pollution)?
In this activity, you will interpret graphs to determine emissions from various sources and determine the source type emitting the most PM10 and PM2.5 in your state.
  1. Select your state from the map to view the state's air pollution data (NOTE: it may take a moment to load the first time you click).
  2. Click through the site and look up the amount of various pollutants in your state to complete the table and answer the questions on the Student Worksheet (move your mouse over the colored column to view the corresponding percentage) .
